WINDOW-SCREEN.

LeansiaQ To all whom t may concern:

Be it known that I, Erasmus A. WARE, a citizen of the United States,residing at Groton, in the countyol` New London, State of Connecticut,have invented certain new and useful Improvements in l/Vindow- Screens;and I do hereby declare the :tollowing to be a full, clear, and cXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in window screens and has for oneof its objects to provide a window screen embodying means of novelconstruction and arrangement by reason ot which it may be quickly andconveniently adjusted to permit of its application to windows of varioussizes The invention further purposes a novelly adjustable window screenhaving an improved means by which it may be securely locked in -itsvarious positions of adjustment so that it may not be removed from thewindow casing by a person stationed outside of the building.

`With the above and other objects of similar nature in view theinvention consists in the construction. combination and arrangement ofparts set forth in and falling within the scope of the appended claim.

In the drawing:

Figure 1 is a front elevation of the improved window screen,

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1,

Fig. 3 is a detail section taken on the line 3-3 of Fig. 1, and,

Fig. 4: is a detail view of the locking device, the same being ininactive position to permit of adjusting the screen sections.

Referring now more particularly to the accompanying drawing, my improvedwindow screen comprises a pair of substantially rectangular framesections 5 and 6, each having stretched thereacross and secured in anysuitable manner a web of wire screening 7. The :trame sections 5 and 6are arranged in a common plane one upon the vother and are slidablyconnected for relative longitudinal adjustment through the medium otplates or guide clips 8 disposed on opposite sides of the adjacent framemember of the secspecieauon f Letters Patent.

tions and secured alternately thereto by screws 9.

Carried by the outer end members of the frame sections 5 and 6 andsecured thereto as indicated at 10 are plates 11, each of which slidablyoverlap the other section so as to permit the adjustment and applicationof the 'screen to windows of various sizes without leaving an open spacebetween the inner end member of the sections and the window casing.

In order to lock the sections 5 and 6 in their various positions ofadjustment there is carried by the inner longitudinal frame bar of thesection 5 a fixed laterally projecting pin 12 upon which is pivotallymounted a locking lever 13. The lever 13 is provided at its upper endwith a reduced handle portion 14: by which it is manipulated, and hasits lower end directed at right angles as indicated at 15 to extendbeneath the inner frame bar of the section 6. The lever is furthermoreprovided with an angle or bayonet slot 15 loosely receiving the pin 12,said slot being so arranged that upon movement of the lever in onedirection as indicated in Fig. 1 the projection 15, of the lower end ofthe lever will act as a fulcrum upon the frame section 6 while the pinwill slide downwardly in the slot to move the sections 5 and 6 intobinding contact one with the other they being in this manner securelyheld against relative movement as is evident. However, when it isdesired to adjust or remove the screen the lever is swung in theopposite direction at which time the pin will ride upwardly in the slotand disengage the projection 15 from the frame 6, the sections beingthus free to move as will be evident by reference to Fig. 4.

What I claim is An adjustable window screen comprising operable to holdthe two sections against In testimony whereof, I affix my signamovementwtl.) resipeeft to each other, and ture, in the presence of twowitnesses.
